How were the Black Hills created?

Answer 1

The Black Hills are known as 'dome mountains. They were created when lava tried unsuccessfully to force a way through the Earth's crust making a large bump. The Black Hills are the much eroded remains of such an event.

Answer 2

The rocks layers of the Black Hills are laid out like a target and the center is a granite core, with rings of different rock types dipping away from the center.

The granite of the Black Hills was formed by magma. The first ring around the core was formed by sedimentary deposits. Then there was a collision which caused the original sedimentary rocks to fold and twist into a vast mountain range.

After that, may layers of deposits and uplifts and erosion have helped form the Black Hills into their current shape.

Answer 3

The Black Hills form an oval dome that is laid out like a target with rings of different rock types dipping away from the center.

The Black Hills were formed by a core of rocks that comprise the Black Hills uplift. The formation of the northern part of the Black Hills uplift also included volcanic activity. Erosion in the Black Hills has helped to expose the different rings around the granite core.

Answer 4

The Black Hills are a landform. Who "made" the Black Hills depends on a variety of beliefs. The Dakota believe that Wankantanka, the chief god, created the earth.

Answer 5

The Lakota called the Black Hills the Pahá Sápa or "Hills that are Black", because, when seen from a distance, due to all the pine trees, the Black Hills appear to be black.
